    I checked my battery today with Coconut battery, and the reading i got today was 100% with an original battery capacity of 5600 mAh, and a current battery capacity of 5674 mAh.

    Is this caused by not being calibrated properly?


    EDIT, its now reading 5701 mAh.

    No, there is nothing wrong with your battery. 5600 mAh is an approximation of the actual battery capacity, it can be much more than what yours is. For example, my 12" PBG4's battery says it has a capacity of 4649 mAh where the approximate (from Apple) is actually 4400 mAh.

    The thing is, I have calibrated it a number of times in the past, and it almost always read that there was around 98% of the battery left.

    98% health on the battery? That's good enough for a battery, besides, the readings found with Coconut battery (or any battery monitor) are entirely accurate. As long as it isn't noticeably lower there is no problem with it.

    Like I said, in the past it has read 98%, but now it suddenly jumped back up to 100%. When i received my macbook and calibrated it and ran coconut battery, it read 100%, with a total 5600 mAh out of 5600 mAh. Then it started to read 98%, even after calibration. Now.. Its reading 100%, but with 5700 mAh out of 5600 mAh.

    I just dont see how it could jump back up, even past the original reading.

    Because cells will get worse or better over time.
